The history of the development of coal liquefaction technique by direct catalytic hydrogenation is divided into three periods as follows.I. From the invention by bergius till the end of the world war I (1913-1945)II. Research after the war, reconsidering bergius method (1946-4960)III. Reacent increasing research in U. S. A.(1965-)Third period is consist of H-coal, synthoil and COSTEAM process, etc. Their purposes of stuyding are all to make heavy fuel for electric power rather than light crude distillate.The auther, who has experience in operating a coal hydrogenation plant at Agoji. North Korea, from 1940 to 1945 as a chief engineer, considered various problems in coal liquefaction in aspects of raw material, procese, design, operasion (control) and reactor materials, and pointed out problems of former reactors. It is also illustrated that the manufacturing cost of oil from direct coal liquefaction may compete with one from crude petroteum, if the products are light crude distillate and LHSV is more than ten. Then there seems to be a possibility for success when the tubular reactor which the auther has devised will be used.In future, the direct coal liquefaction plant may be expected to be mainly composed of numerous tubes like as tubular reactor or heat exchanger.
